The fxp driver supports the following media options:
Set full duplex operation
Note that 100baseTX media type is not available on the Pro/10. For further information on configuring this device, see ifconfig(8).
The fxp driver supports reception and transmission of extended frames for vlan(4). This capability of fxp can be controlled by means of the vlanmtu parameter to ifconfig(8).
The fxp driver also supports a special link option:
Some chip revisions have loadable microcode which can be used to reduce the interrupt load on the host cpu. Not all boards have microcode support. Setting the link0 flag with ifconfig(8) will download the microcode to the chip if it is available.
There are not enough mbufs available for allocation.
"fxp%d: device timeout"
The device has stopped responding to the network, or there is a problem with the network connection (cable).
"fxp%d: Ethernet address ff:ff:ff:ff:ff:ff"
In some Alphas (AXPpci and Multia) you must tell the driver to use (slower) I/O rather than memory to access the card. Create, if it does not yet exist, and add to the file /boot/device.hints the line "hint.fxp.0.prefer_iomap= "0"".
